For anything worth doing, there will always be several excuses why it should not be done. Each excuse for failure will become a decorating star on the crown of a successful person; and the more of them there are, the more beautiful will be the crown at last for such person.
Do not let the height of the challenge in front of your goal deter you from reaching for it; rather let every reason why you can’t do it become a reason why you must do it. The greater the obstacles, the more fascinating the testimony will be when you tell it at the end of the day.
When many persons around you say you can’t, it doesn’t really mean that you cannot, or will not; it only means you have more persons to prove wrong, and many reasons why you should do it.
Turn you excuses and oppositions into inspirations, and let them fan into flame the fire of determination towards that goal.
